GYROSCOPIC TOY Filed Sept. 20, 1946 Patented June 27, 1950 j" UNITED sTArEs PATENT ornosoorro TGY 'Edward T. Stahl, Santa-Ana, Calif. "app c tion September 20, 1946,Serial'No.-i698;273'

This invention relates to a toy and more particularly and specifically to a new and improved gyroscopically balanced walking toy which has as its primary object the provision of a toy of the character described which is a rope walking toy maintained in an upright position by a. fluid operated gyroscope.

Another object of this invention is the provision of such a toy which could be of educational value to children.

Still another object of this invention is the provision of a toy of the character described which is of simple, durable and inexpensive design.

Further advantages and improvements of this invention will readily appear to those skilled in the art upon examination of the following description when read in the light of the accompanying drawings in which:

Fig. 1 is a vertical section taken through a side elevation.

Fig. 2 is a horizontal section taken on line 2-2 looking in the direction indicated by the arrows.

Fig. 3 is a vertical section taken on line 3--3 of Fig. 1 looking in the direction indicated.

Fig. 4 is a top plan view of the toy.

Referring now to the drawings A designates the main body of the toy which in this instance is.

designed to represent a clown but could be made in any form without departing from the spirit of the invention.

The main body A is formed from two sections I and 2 which are separably connected by a suitable means such as the inset screws illustrated in the accompanying drawings.

A vertical slot 5 carried upwardly from the center of the base 6, of the body A, houses a grooved wheel 1 which is rotatably mounted on the horizontal pinions 8 and 9. This wheel supports the toy body on the flexible cord or cable I!) which is secured to a stationary object at II and grasped by the operator at the other end thereof. The operator, by raising and lowering the free end of the cord I0, will cause the toy to move back and forth on cord I0.

Formed within the toy body and running between both halves I and 2 is a horizontal cavity B whose axial center is on line with that of the body A.

Secured within body A adjacent the upper and lower sides of said cavity and on its vertical center line are two bearings I2 and I3 which receive a shaft I4 on which is mounted for horizontal rotation a gyroscopic wheel C. This wheel is provided about the circumference of its upper side With a series of notches or buckets I5.

zclaims. (01. 46-550 Originating at the top of the head of the body, which is formed to provide a mouthpiece, and running downwardly and rearwardly to the outer, upper edge of cavity B is a tubular passage D which terminates at the cavity in a restricted throat or nozzle I6 which is disposed downwardly to and in the direction of rotation of the wheel buckets.

The operator, by blowing a, blast of air into passage D will cause the rotation of the gyroscopic wheel 0 as the blast of air is directed against the buckets I5 by the nozzle I6. When the operator removes his mouth from the mouthpiece, some of the blast of air which causes the rotation of the gyroscope wheel will have leaked out between the opposing faces of the sections I, 2, of the body A, and the remaining portion of the blast will escape through the passageway D.

This rotation of the wheel C enables the toy A to maintain an upright position on cable I0 by reason of gyroscopic principle, and successive blasts of air at spaced intervals will maintain the toy A in its upright position on the cable II].

It can be seen that examination and repair to the working parts can be easily accomplished by the removal of I from 2.

Having thus described and explained this invention I claim:

1. In a gyroscopic toy, a body including a pair of sections arranged in facing relation with respect to each other and secured together, the opposing faces of each of said sections being provided with a semi-cylindrical recess therein, said recesses cooperating to provide a substantially cylindrical cavity in said body, and a gyroscope positioned within said cavity and mounted on said body for rotation about an axis extending longitudinally of said body, said gyroscope including a wheel having a plurality of buckets positioned adjacent the periphery thereof for effecting the rotation of said gyroscope as a jet of air impinges said buckets, one section of said body being provided with a tubular passageway therethrough having one end in communication with the atmosphere and having the other end in communication with said cavity, and a mouthpiece secured to said one section adjacent said one end of said passageway, whereby the gyroscope is rotated upon blowing into said one end of said passageway.

2. In a gyroscopic toy, a body including a pair of sections arranged in facing relation with respect to each other and secured together, the opposing faces of each of said sections being provided with a semi-cylindrical recess therein, said recesses cooperating to provide a substantially 3 cylindrical cavity in said body, a gyroscope positioned within said cavity and mounted on said body for rotation about an axis extending longitudinally of said body, said gyroscope including a wheel having a plurality of buckets positioned 5 adjacent the periphery thereof for efiecting the rotation of said gyroscope as a jet of air impinges said buckets, one section of said body being provided with a tubular passageway therethrough having one end in communication with the atmos phere and having the other end in communication with said cavity, and a mouthpiece secured to said I one section adjacent said one end of said passageway whereby the gyroscope is rotated upon:

blowing into said one end of said passageway, said other end of said passageway being restricted to provide a nozzle for directing the air blown into said passageway against said buckets.
